  1. 1. Spectroscopy of the Globular Cluster M30

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Kilian Hikaru Scheutwinkel; [2019]
    Keywords : Spectroscopy; Globular Cluster; M30;

    Abstract : Globular Clusters contain very old metal-poor stars in different evolutionary stages evolved from the same primordial cloud. Signatures of atomic in stellar interiors are studied in the metal-poor GC M30. Furthermore, traces of cluster internal pollution depleting alpha elements e.g. READ MORE

  2. 2. Fast Simulations of Star Cluster Evolution

    University essay from Lunds universitet/Astronomi

    Author : Lina Warntoft; [2019]
    Keywords : star cluster simulation numerical method; Physics and Astronomy;

    Abstract : The evolution of globular star clusters tells the history of the formation of galaxies, how stellar streams might have formed and how the future of the Universe might look like. Although the general theoretical background of the evolution is well understood, it is difficult to conduct accurate and realistic computer simulations of objects containing thousands of interacting bodies.

  3. 3. Can tidal interactions produce MGC1?

    University essay from Lunds universitet/Astronomi; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Eric Andersson; [2018]
    Keywords : globular cluster; MGC1; Andromeda; M31; galaxy; dwarf galaxy; tidal interactions; Physics and Astronomy;

    Abstract : The globular cluster population of large spiral galaxies can be divided into two populations: one population which formed in-situ and one which has been assembled through capture of clusters that have been tidally stripped away from other galaxies during close encounters or mergers. In this work, I focus on the globular cluster MGC1, which is orbiting the M31 galaxy. READ MORE

  4. 4. Spectral investigation of the globular cluster M30

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Scheutwinkel Kilian Hikaru; [2018]
    Keywords : M30; globular cluster; spectroscopy;

    Abstract : Globular cluster studies suggest that a signature in the spectra of RGB stars in a globular cluster are anti-correlations in Mg-Al and Na-O. In this work, a small sample of 12 RGB stars of the globular cluster M30 is investigated using VLT-UVES high-resolution spectrograph. READ MORE

  5. 5. The consequences of dwarf galaxies colliding with the Milky Way

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik; Lunds universitet/Astronomi

    Author : Ryan Skeoch; [2014]
    Keywords : Physics and Astronomy;

    Abstract : I simulate the collision of satellite galaxies with the Milky Way and observe the effects that this has on the orbits of the globular cluster populations within both the Milky Way and the satellite galaxies. This is done in order to investigate whether some of the Milky Way's globular clusters could have been donated from satellite galaxies which have been tidally stripped, since it is believed that the Sagittarius dwarf spheroidal galaxy is being tidally disrupted and that some of its globular clusters have been tidally stripped from it (such as Pal 12 and NGC 4147).
